I just shook my head.
Judge for yourselves.

You might want to just post a link, the forum does not allow embedded video viewing.

I like his plastic gloves. If those catch on fire he will need major skin grafts. I use an oxy acetylene and can weld those joints in 1 minute.

I've never done that and I have a question.
Why does it take so long for the copper to get up to temperature?
Was he scaulding the metal or is that how long it takes?
If so...why?

It never takes that long to solder that size copper fittings.

What am I missing?

he was blowing nitrogen thru at 10 psi when we normally use 1 psi. blowing away the heat and he is using a large blowtorch type flame. I prefer a smaller hotter oxy acetylene precision tip/flame. He cooked it good.

Oxy/ace is faster Bud. Solder has a much lower melting point then the 15% silphos used so it takes what it takes to get the pipe up to 1100+ degrees. Using oxy/ace those 2 elbows would have been done in about 1 minute instead of the 6 minutes it took using a B tank.

Yep, too much nitro at first, and he had the torch too far a way. I can braze 1 3/8" faster then that with a Turbo.

He should use a flow reg to flow his nitrogen.

prevents carbon from forming inside the joint and later getting into the system and plugging up components. if U weld in an oxygen free environment carbon does not build up. nitrogen displaces the oxygen.

Anybody notice the fact he is using an open flame close to some LARGE battery chargers for those forklifts. Last time I heard batteries can give off explosive gases when charging and KABOOM.

Safety equipment (eye protection in this case) is not a pre-requisite south of the border I suppose?
